Figure 3

Tree structures for the generalized Dirichlet distribution. Figure (a) depicts the generalized Dirichlet tree structure of the compositional vector (Y1,Y2,Y3) following a generalized Dirichlet distribution, whereas Figure (b) depicts the tree structure of the compositional vector (Y3,Y1,Y2), also following a generalized Dirichlet distribution. The generalized Dirichlet models for these two nesting structures could potentially be very different. Within each nest, the variables are modelled as beta distributions, conditional on the parent node.
